OAR-LOCK.

Specification of Letters Patent. Patqgnfigd Dec, 15, 15)],4;

Application filed August 4, 1914. Serial No. 854,945.

To all whom it may concern Be it known that LICHARLES Enwnnns, a citizen of the United States, residing at Gouldsboro, county of Wayne, State of Pennsylvania, have invented an Improvement in Oar-Locks, of which the following is a specification.

This invention has for its object to pro-' vide an oar lock adapted for general use and especially adapted for use upon fishing boats, which will enable the user to vary the fulcrum of the oar so as to give more or less knee-room or changed positions of the body in rowing and which will retain the oar in operative position when released by the user.

Vith these and other objects in view I have devised the novel oar lock which I will now describe, referring to the accompanying drawing forming a part of this specification and using reference characters to indicate the several parts.

Figure 1 is an elevation of one form of my novel oar lock with the shank of the car in cross sect-ion, different positions of the oar holder being indicated by dotted lines; Fig. 2 an elevation as seen from the right in Fig. 1, showing a changed position of the oar holder; Fig. 3 a perspective view illustrating a variant form of car holder, and Fig;

4 is a detail view on an enlarged scale showing an, oar shank slotted transversely to receive an oar holder of the form illustrated in Fig. 3.

1O denotes the shank of my novel oar-lock which is adapted to oscillate in a hole in the gunwale of a boat, not shown, and is ordinarily provided with a collar 11 upon which -it rests andwith a hole 12 inits lower end through which a pin, not shown, may be passed to'retain it against accidental removal. The upper end of the shank is provided with a head 13 lying in the vertical plane and the oar holder is provided with a corresponding head 14 pivoted on one side of the head of the shank, so as to adapt the oar holder to oe swung in the vertical plane. The oar holder may comprise a curved arm 15, adapted to inclose the shank of an car, as in Figs. 1 and 2, said arm being offset from the pivot, indicated by 16, so that in use the shank of the car will lie either above or below the pivot; or the car holder may comprise a straight arm 17 standing outward from the head at a right angle, as in Fig. 3, and adapted to pass through a transverse slot 18 in the shank of the car, see Fig. 4.

'bility of displacement.

In the form illustrated inFigs. land 2, the car may be provided with a collar-l9] to limit its downwardly sliding movement in the car holder; In the form illustrated in Figs. 3 and 4, the oar holder may be provided with a hole 20 and the car 21 with a vertical hole 22, said holes when in alinement being adapted to receive a pin, not shown, to retain the oar against the possi- Tt should be noted that the'transverse slot in the car in the second form does not materially weaken the car or lessen its ability to withstand the transverse strain of rowing.

A vitally important feature of the invention is that it enables the user to fulcrum the oar in four different positions; that is, two forward and two rearward positions, or two raised and two lowered positions. The change from a raised to a lowered position, and vice versa, will be understood by comparing the 'full line position in Fig. l with: the full line position in Fig. 2, or the full line position in Fig. l with the dotted position immediately above it, or the full line position in Fig. 3 with the dotted position in said figure. When the oar is removed the user simply swings the car holder from one position to theother, as may be required. The change from a forward to a rearward position, and vice versa,-will bereadily understood by comparing the full line position in Fig. 1 with the dotted position in horizontal alinement therewith in said figure, or the full line position inFig. 3 with the dotted position in said figure. When the oar is removed, the user simply gives the car look a half turn in its bearing in the gunwale, in addition to which, if he desires to raise or lower the fulcrum of the oar, he swings the car holder on its pivot." These adjustments of the position of the car holder add greatly to the comfort and convenience of rowers in use, as they are not limited to a single fulcrum point for the car, without regard to whether their legs are long or short, and by shifting the fulcrum point forward or backward as may be required they are enabled to determine the most com, fortable position or inclinationof the body in rowing. j

Having thus described my invention 1 claim:
